The state of Tamaulipas has nearly 1.7 million hectares of agricultural land, and 56% of this area is located in the Northern part of the state, close to the Lower Rio Grande Valley in Texas. Cotton, is an important crop, with boll weevil, Anthonomus grandis Boheman. as a most significant factor for producing economic yield. Finding other type of strategies to reduce cotton boll weevil population is very important, because the other major pests (Heliothis spp and Spodoptera exigua ) in most instances have a good natural control, and the presence of Boll weevil means chemical control which disrupts in most cases the equilibrium of natural enemies and insect pests.
